LMK03001 about evaluation board

Toshiyuki

Hi,

Our Customer have a question about the value of capacitor in evaluation board.

To care for RF immunity,they may change the value of capacitor at VCC pin/10uF and other pins/100pF.

For example, VCC pin/10uF could be changed 100uF?  The other pins/100pF could be changed 0.1uF or 10uF?

Is there anything that we should be careful of the value of capacitor?

Best Regards,

kato

    Hi Kato-san,

    Yes, it should be OK to increase the bulk decoupling from 10uF to 100uF, but use Low ESR caps for effective supply decoupling.  Otherwise, you can use multiple 10uF or 22uF caps in parallel.  For the 100 pF bypass caps, you can use 0.01 uF or 0.1 uF per VCC pin. 

    Regards,
